thanks, i will try and find one around me. just trying to keep it as simple as possible. want to build a bridge over a bog in my back yard to get to rest of my property and some trails (for walking the dogs). i liked the strength of the lumber used at Borderland. a 12' long section with no middle supports barely sags with me (260+lbs) on it.

Hey No Skills, the Friends bridges are 2X12 PT lumber (used for both the beam and & the top deck), with 14" X 14" blocks at either end for footings. The 14X14 blocks were cut from pressure treated timbers (they were donated by a big-dig contractor). One of my better bridge designs in B'land.

Thanks CP. A little surprised to hear they are just 2x12 pressure treated. I measured the thickness the other day and they were well over 2" thick. Would have thought 2x12 would be 1 3/4" thick, at most. Maybe they were bloated I'm going to use cut up stumps for some of the footings, will probably need to find some timber blocks though.

If you are looking to put a bridge on State Park land I would check with the local Boy Scouts, they make a lot of the bridges for the SPs. I know this because some friends and I spent our hard earned money to built a well thought out safe, wide and secure bridge in a local SP only to have it ripped out a year later for a new bridge built by the local Boy Scouts. I appreciate the work that they do but if i was going to do it again, i'd check with them so we didn't waste our time and money on a bridge that they had all ready planned to build. We could have used our lumber to fix a different area.

Or - you could check with the State Park managers (since it's their land to manage), and see if they have bridge standards you need to follow, find out if someone else has already signed up to do that work, and/or get approval to construct anything on their land before you start...
